Research on Health Diagnosis Technology for the Walking Department of Power Concentrated EMU
With the continuous expansion of the operating scale of power concentrated high-speed trains in China,the pressure of daily maintenance and operation management of the running gear of high-speed trains is becoming increasingly prominent.The intelligent operation and maintenance of the running gear of high-speed trains through health diagnosis technology has become a key direction need various operating units are actively exploring.Based on the issues of daily operation,maintenance,and health management of the running gear of the high-speed train unit,a health diagnosis system for the running gear of the high-speed train unit is designed and proposed in the article.This system is based on an anomaly detection model,which combines real-time operating feature parameters,historical feature parameters,and running gear maintenance data to determine the type and degree of damage caused by faults,automatically evaluate the degradation evaluation indicators of monitoring components,clarify the health status of monitoring components,and intelligently generate the optimal maintenance decision.The actual vehicle verification shows that the system can achieve the fusion analysis and application of multiple information on the running parts of the power concentrated multiple unit,providing effective reference information for the health management of the running parts of the multiple unit,and providing effective guidance for monitoring component maintenance.
